Three adsorption isotherms of SO 2 on ice were measured at −3°, −11°, and −30°C in the SO 2 concentration range of 0.3 to 6 ppmV. The isotherms indicated that there is a strong increase of adsorption as the temperature rises toward the melting point. This behavior may correlate with the presence of a "quasi‐liquid" layer on the surface of ice. If this behaviour is typical of impurity adsorption on ice, it is important in the processes that govern the acquisition, transport and storage of atmospheric pollutants by snow.
